> Subject: [dpdk-dev] [PATCH v5 1/2] net/mlx5: fix crashing testpmd on null drv
> opts
>
> mlx5 implements mlx5_flow_null_drv_ops to be used when a specific flow
> typei/driver is not available or invalid.
> This routines return error without modifying the rte_flow_error parameter
> passed to them which causes testpmd, for example, to crash.
> This commit addresses the issue by modifying the rte_flow_error parameter
> in theses routines.

> Fixes: 0c76d1c9a18d ("net/mlx5: add abstraction for multiple flow drivers")
> Fixes: 684dafe795d0 ("net/mlx5: add flow query abstraction interface")
